Sometimes, we get an error when we are trying to use apt-get in Ubuntu–>
E: Could not get lock /var/lib/dpkg/lock – open (11 Resource temporarily unavailable)
E: Unable to lock the administration directory (/var/lib/dpkg/) is another process using it?
You can delete the lock file using this commands:
# sudo rm /var/lib/apt/lists/lock
This line will delete your lock, You may also need to delete the lock file in the cache directory
# sudo rm /var/cache/apt/archives/lock
# sudo rm /var/lib/dpkg/lock
After that, try again apt-get and you will be able to access it.
